}Frequently Asked Questions
How many disposable email providers does ValidoAPI cover?
ValidoAPI covers 10,000+ disposable email domains and providers, including the most popular ones like Mailinator, TempMail, Guerrilla Mail, 10 Minute Mail, YopMail, Trashmail, and thousands more. The database is updated continuously.
What happens if a new disposable provider launches?
Our team continuously adds new disposable providers to the database. We also use pattern-based detection to identify new domains using common disposable infrastructure, even before they are added to the explicit list.
Can I still accept free email providers like Gmail?
Yes. Disposable detection only flags temporary email services, not free providers like Gmail, Yahoo, Outlook, or Hotmail. You can separately use our free_provider flag if you want to detect free email services.
Is disposable detection included in the free plan?
Yes. Disposable email detection is included in all plans including the free Starter tier.
What should I do when a disposable email is detected?
Common approaches include showing an inline error asking the user to use their real email, preventing form submission, or silently flagging the lead for manual review instead of hard-blocking.
